| Addressing the technical demands of geological mapping in complex terrain conditions, this study establishes a comprehensive technical workflow based on high-resolution remote sensing imagery and digital elevation models （DEM ）, integrated with multi-source data including measured geological boundaries and lithological specimens. The workflow encompasses key procedures such as data preprocessing, spatial registration, feature extraction, and fusion analysis. By designing a multi-source data fusion algorithm, the approach effectively combines the macroscopic spatial coverage advantage of remote sensing data with the microscopic accuracy validation advantage of geological survey data, achieving mutual calibration and complementary enhancement of multi-source information. This technology is primarily applied to geological structure interpretation, lithological classification, and stratigraphic boundary identification. The results demonstrate that the fusion technique significantly improves the quality and efficiency of geological mapping, and the generated geological maps exhibit a high degree of consistency with ground validation data. Through complementary advantages, the integration of multi-source remote sensing and geological survey enables high-precision acquisition and comprehensive analysis of geological information in complex terrain environments, thereby providing effective technical support for enhancing the efficiency of geological mapping. |
